To ali 'whom it may concern:

Be it mown that l, CHAnnes W. Kmson, e citizen ci"v the United States,residing et Sturgis, in the county of St. Joseph und o Stete ofMichigan, have Vinvented certain new end useful lm rovements in CurtainRods, of which the ollowing is-e specificetion.

This invention relates to en improved rod adopted for henging curtainsand the like and relates particularly to that type of rods of thischaracter commonly termed llat and which are formeel of sheet metal,said rods having n :Het well end an op osed longitull slotted wellpareils with and spaced om the hat Well.

The object oi the present invention is to so construct the rod es tosecure the following advantages, viz:

i. Substantially balance the amount of metal in the slotted wellof therod with the amount thereof contained in seid Vhet w end to accomplishthis without eppreciebly varying the cross-sectional shape or dimensions et the rod.

2. To ohviste sherp or hurred ed of the motel bordering the slots andprovi ev rounded edges in piece thereof.,

3. To provide rods ot 3@ tions extending transversely to the mainportion thereof, .wherein the portions of the slotted well et the rodcomprised in or disposed contiguous to the bend, are smooth and devoidof buckling or distortion, condition resulting from the balancing of themetal, es aforesaid.

t. To provide e rod of the general shape enclucontour aforesaid which isstiil'er and stronger than heretofore and `less liable to distortion orindentation bordering the slot.

5. To provide n roflconsisting of e. plu-v Sti single straight rodhaving the dont e-thick edge portions of its Vflanges thecross-sectionnl shape mentioned end provided with end poralong the'walls relitti7 ot similar telescopic-,elly interlitti drawings,

oset from the :nain portions thereof, as he previous pereJ sph' setforth, to thereyo resulting troni such o'set.

The invention me he variously embodied, the preferred eniho irnentsthereof being illustretecl in the accompanying drawings,

wherein:

Curtain rods of the general cross-sectional shepeend contour-LesV 'those.shownin the element are ofsingle thickness endl present sha1-@rawedges, have been lon on the market, being'furnished in streig t iecesend in pieces having at least one en bent to extend substantiallyperpendicularly to the main portion of the piece,

The sh ,raw edges are obviously jectionable or menjr reasons and thesinglethick snges have rendered buckling thereof in hendingthe rodsalmost unavoidable and rendered denting and distortion of said nangesnary use endV handling of the rods.

As shown, the rods of the present inven-v tion dier from those heretomost generally Vmerketeth'in that the opposed edge portions which borderthe slot 8,

ci the iienge Lswhich extend largely parallelwith the Vmein net-wall 2,constitutin usually, the only visible which extends from enel to end etthe rod, are rendered doublethick hv toldin over the extreme ai evrtions et of sei enges to lie Het upon "n e y portionsthere'of and,preferably, upon easy of accomplishment in the ordi' but wherein, theenges ot' each ice face of the rod, .an

iccV

' ythe inner faces of the latter. i, The slot 3 is thus bordered bysmooth rounded edges and s aid flanges are rendered far stiffer and, byreason of thus substantially balancing the amount of metal in theslotted wall of the rod with that in the flat wall 2 thereof, thebending of the end portions of the rod to extend transversely to themain portion' thereof, may be accomplished without the buckling of theflanges occurring in such bending of single-thick flanged structures andindentation and other distortion of said Han es in the ordinary uses andhandling of the rod is greatly reduced if not entirely obviated. i.

Where two bent-end rod sections are tele-l scopically joined to form atelescopically extensible structure, the edge-portions of the flanges'ofthe inner and smaller section or member A are, preferably, folded overinwardly and those of the outer and larger section B, foldedY overoutwardly, as shown rinFig. 6. l y l Preferably, however, for greaterneatness of appearance and further strength and stiffness, theconstruction shown in Fig. `5

l is adopted, the latter consisting in off-setting the double-thick edgeportion of' the inner section C of the rod inwardly, both as indicatedat 5, a distance equal to about onchalf the thickness of the metal ofwhich the rod is com osed and similarly off-setting this portion of) thelarger and outer section D outwardly.

The several embodiments shown in Figs.v 5 and `6 permit the `telescopingsections to be interfitted without springing the flan es thereof tocompensate for the double-thick edge portions as would otherwise berequired.

Where' straight lengths of rod without bent end portions are employed,the doublethick edge-portions of the flanges are, preferabl offset toaccord with either the member or the member D, as desired.

I claim as my inventiom- 1. A curtainrod comprising ai? hollosheet-metal structure including a continuous flat front Wall and acontinuous longitudinally slotted rear wall parallel with Aand spacedfrom said front wall, the rear-wall portions bordering said slotpresenting continuous rounded edges "and continuous laterally offsetportions of double the thickness of other wall portions, to therebysubstantially equalize the amount of metal in said rear wall with theamount thereof in said front wall.

2. A rod adapted for hanging curtains and the like, comprising av ho lowsheet metal structure having a substantially flat wall ybordered bycontinuous substantially semiwalls terminatin in opposed each other, tothereby provide a continuous slot between said flanges, the opposedcontinuous edges of said flanges consisting of two thicknesses of themetal and presenting continuous rounded opposed edges bordering saidslot, the opposed surfaces of the double-thick portions 'of said flangesbeing in close contact throughout their areas, to thereby render theexposed surfaces of said double-thickv portion parallel with each other,said double-thick portions of said flanges od-set from the main portionsthereof and parallel therewith.

3. A telescopically extensible rod adapted for hanging curtains and thelike, consisting of a plurality of members of similar crosssectionalshape and different cross-sectional dimensions to adapt the smaller tobe telescopically associated with the larger thereof, each of saidmembers having a substantially flat wall bordered by continuoussubstantially semi-cylindrical side walls terminlalting in opposedflanges substantially para el from, andsp'aced from leach other, tothereby provide a continuous slot between said flanges, the opposedcontinuous edges of said flanges consisting of two thicknesses of themetal and presenting continuous rounded opposed edges bordering saidslot, the opposed surfaces of the double-thick portions of said flangesbeing in close contact throughout their areas to thereby render the.exposed surfaces of said double-thick portion parallel with each other,said double-thick portions of -said flanges off-set from the mainportions thereof and parallel therewith, said double-thick portions ofthe flanges of the smaller of said members being off-set inwardly andthose of the larger outwardly relatively to'the flat walls thereof, tothereby permit the telescopic association of said members without sringing the flanges of either thereof.

4. A rod adapted for hanging curtains and the like, comprising a hollow,sheet metal unit having a continuous flat wall and a continuouslongitudinally slotted wall arallel therewith, the portions of saidastnamed wall bordering said slot being off-set from and parallel withthe balance thereof, said off-set portions being coextensive with thelength of the said slotted wall and of double-thickness throughout andpresentin olpposed, rounded free edges bordering sai s ot. v

5.- A curtain rod including a member havingan end portion disposed toextend substantially transversely of the main portion thereof, one wallof said member being at and adapted to be vertically disposed throughoutits length when the rod is positioned to support a curtain or the like,said member having continuous flanges parallel with said wall and spacedtherefrom, the free with said flat wall and spaced thereedges of saidflanges opposed to and spaced said anges with the amount of metalconfrom each other to -provlde a continuous slot tained in said flatwall, the opposed free extending-from end to end*v of said memedges ofsaid flanges being rounded, said 10 ber, the free edge portions of saidHanges double-thickness of 'said edge-portions beingv 5 being of doublethe thickness ofthe balance continuous throughout the length of saidthereof and of said flat welvlvto thereby subiangesa stentially balencethe amount of' metal in CHARLES W. jKRSCH.
